Encoding in Java

Question

Hi, I have a string with special characters in Java.

"[^\\"]*\\"

I want to convert it to HTML entities like this:

"[^\\"]*\\"

How this could be achieved in Java?

Answer 1

You need to parse the input string character by character and look for particular ones that you want to convert. When you find a match, simply replace that character with the HTML entity.

Answer 2

Use String.replace() as needed:

"[^\\\"]*\\".replace("\"", """);

Answer 3

Apache Commons Lang includes a helper for encoding HTML. StringEscapeUtils.escapeHtml() should do the trick. According to the javadocs it "Supports all known HTML 4.0 entities, including funky accents".
